A fund started by the Winklevoss brothers, Tyler and Cameron–who are best known for their legal clash and settlement with Facebook, and their rowing careers–led a $1 million financing for Hukkster, a New York e-commerce start-up. The seed round marks the second investment for Winklevoss Capital Fund, a family fund without outside investors.

As The Wall Street Journal previously reported, earlier they backed SumZero, a site that brings investors together to share trading ideas and research. Hukkster is their first investment in a consumer application.

The Hukkster website and service lets online shoppers “hukk” or mark items that they covet, from stores across the Internet, and receive alerts by email or text message when the prices on those items drop to a level they can afford, or feel is fair.

As VentureWire previously reported, Hukkster co-founders Erica Bell and Katie Finnegan worked in fashion and retail companies, including together at J. Crew Group, and later in the retail consulting practice of A.T. Kearney. Their earlier backers in the seed round, which reached $1 million, hailed from retailers TUMI Holdings and Henri Bendel.

With the new seed money from Winklevoss Capital Fund, the Hukkster team will complete the development of their mobile app, continue marketing and developing relationships with online retailers, according to the co-founders.

“This gives us the power to make the splash we were hoping to make, while we cover all our engineering and other costs,” Finnegan said.

Currently, the Hukkster app works with major fashion brands and stores online from Asos.com to Nordstrom.com, but has not yet integrated with Amazon.com or other e-commerce juggernauts. It has 10,000 monthly active users.

Tyler and Cameron Winklevoss said their fund remains a family fund, without capital from outside investors.

“When you’re investing your own money, there’s something fun about it. We have the flexibility to jump verticals, and invest patiently in entrepreneurs and businesses that we can help push into the mainstream,” said Cameron Winklevoss.

Beyond this deal, the Winklevoss twins have plans to open a brick-and-mortar office in New York’s Flatiron neighborhood this season. The impact of Hurricane Sandy prevented them from being open sooner, they said.

“We took out over 5,000 square feet, and that means if you’re an entrepreneur we want to get to know, we can help you. You can desk with us,” Tyler Winklevoss noted. “And of course, we think we have a lot to offer start-ups because of our Facebook experience in terms of marketing, publicity, legal and company formation.”

The Winklevoss twins are, currently, the only two managers of the fund. They will be building up support staff, they said, after the doors open in Flatiron.

(Correction: The Winklevoss brothers’ fund led the $1 million total seed round for Hukkster, which was recently extended from $250,000. A previous version of this post said the fund provided $750,000.)
